WORK-GUIDE FOR SEWING-MACHINES.

Specification of Letters Patent.

Patented Dec. 24,1907.

Application filed October 26, 1906. Serial No. 340,767.

To all whom it may concern:

Be it known that I, LOUIS N. BISHOP, a citizen of the United States,residing at Dayton, in the county of Campbell and State of Kentucky,have invented new and useful Improvements in Work-Guides forSewing-Machines, of which the following is a specificatlon.

This invention relates to work guides for sewing machines, and theobject thereof is to provide a work guide for producing in a ready,feasible and convenient manner uniformity in curved shapes whenmanufacturing articles of wearing apparel or other articles ofmanufacture for. which the work guide is applicable.

A further object of the invention is to provide a work guide-which willcause the work disposed over the guiding surface to retain aconcavo-convex or bulged contour which is particularly advantageous inlining structures for application over the rounded parts of a body, suchfor example as the shoulders, over the breast and other parts requiringa concave or convex contour.

A further object of the invention is to provide a work guide which isparticularly advantageous for sewing seams where one length of cloth isdesired shorterthan the other.

With the foregoing and other objects in view, the invention consists ofthe novel construction of work guide as hereinafter more specificallydescribed and illustrated in the accompanying drawin s, wherein is shownan arrangement of wor guide in accordance with this invention, but itwill be understood that changes, variations and modifications can beresorted to which come within the sco e of the claims hereunto appended.

n describing the invention in detail reference is had to theaccompanying drawings wherein like reference characters denotecorresponding parts throughout the several views and in which Figure 1is a sectional view through the bed-plate of a sewing machine showingone form of work guide in accordance with this invention. Fig. 2 is alike view of another form. Fig. 3 is a perspective view of the bed-plateshowing the form of guide illustrated in Fig. 1. Fig. 4 is a viewsimilar to Fig. 3 of the form of guide shown in Fig. 2. Fig. 5 is a topplan of Fig. 1. Fig. 6 is a perspective view showing one form of adetachable work guide. Fig. 7 is a sectional view thereof.

Referring to Figs. 1 and 3 of the drawings,

1 denotes the table and 2 the bed-plate of a sewing machine, thebed-plate being suitably secured to the table and having one end thereofdepressed, as at 3, in a concaved manner so as to form a concavedguiding surface which constitutes a guide for the work. The depressedportion of the bed-pl ate 2 ap proximately centrally of one end thereofis slotted to permit of the operation of the feed and also to receivethe throat plate 4, the latter being flat.

Referring to Figs. 2 and 4 of the drawings, the reference character 5denotes the table and 6 the bed-plate of the sewing machine. The latteris flat and at one end approximately centrally thereof is formed with aU shaped slot 7, and in the slot 7 is secured a removable throat platehaving the sides and one end depending in a curvilinear manner, as at 8,and which terminate in the flattened portion) at the bottom of thethroat plate, the said flattened portion 9 being substantially of awidth equal to the length'of the feed. The throat plate is provided withan opening 10 to permit of the operation of the feed 11.

In Figs. 6 and 7 of the drawings, a removable work guide is shown, andwhich is ada ted to be secured to the bed-plate 12. he guide shown inFig. 6 comprises a pair of side portions and an intermediate ortion, thelatter being indicated by the reference character 13, is flat andterminates in the side ortions. These latter are substantially o'inverted V-shape in cross section and are indicated by the referencecharacters 14, 15. The intermediate portion 13 is provided with a slot16 to permit of the operation of the needle and feed, and is furthermoreprovided with a pair of openings 17 through which extend holdfastdevices for detachably securing the work guide in position. Each end ofeach of the. side portions 14, 15 is beveled, as at 18, whichfacilitates the work in as much as there is no obstruction to thesliding of the material over the guide. Owing to the constructing of theside portions of V-shape in cross section and the intermediate portionof the guide flat, which rests directly uponthe bedplate of the sewingmachine, it is evident that the opposing walls of the side portions ofthe guide and the intermediate portion 13 form a depressed workingsurface for the material in by producing the hollow curved shape deasmuch as the material has to ride over the apex of one side portion, thendown over one wall thereof, over the intermediate portion 13, and thenup over the inner wall of the other side portion, and then over the apexof the said last mentioned side portion. I

The guide as shown in Fig. 6, when used, is slipped over the top of thetable of a sewing machine below the needle and then detachably securedin position.

Any of the forms of work guides as shown has its guiding surface of suchcontour that the work when disposed thereover will be made to retain aconcavo-convex or bulged contour, as will be evident, and it will alsobe evident that such construction of guide is very advantageous whenforming parts requiring a curved contour, and furthermore when sewingseams through two lengths of cloth when one length is desired to beshorter than the other. By the employment of a work guide in accordancewith this invention the same overcomes the present mode of formingcurved parts, the procedure being to hold the parts together to form thecurved shape, that is to say, when the cloth is being sewed, theoperator holds the feeding end of the cloth aloof from the table of themachine whereas, if a work guide in accordance with this invention isemployed, the material would simply follow its course downwardly andupwardly over the guiding surface, thereslred.

What I claim is:

1. A work guide for sewing machines having a pair of side portions and adepressed intermediate portion, said side portions having beveled ends.

2. A work guide for sewing machines comprising a guiding surface havinga flat intermediate portion terminating in side portions, each of whichextends upwardly and outwardly at an inclination, said intermediateportion constituting a seat for the presser foot and in connection withthe sides adapted to impart a curvilinear shape to the work, saidintermediate portion of the guiding surface having a slot at its bottomto allow of the operation of the needle and feed.

3. A work guide for sewing machines hav ing a pair of upwardly extendingside portions, the outer and inner faces of which extend at aninclination, and a fiat intermediate portion terminating at the bottomof the inner face of each of the side portions, said intermediateportion having a slot to allow of the operation of the needle and feed.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
